As I integrate the useNavigate hook within React to guide users to a specific page post-login, an unexpected infinite loop arises. Most sources online recommend utilizing the useNavigate hook inside a useEffect block; however, this method triggers a Warning: Maximum update depth exceeded issue. This warning occurs when a component invokes setState inside useEffect without either having a dependency array or if one of the dependencies changes on each render.
An intriguing observation is that the max depth warning only surfaces after the second login attempt. In simpler terms, everything functions correctly during the initial login session upon server and client startup, but subsequent logins trigger the annoying maximum depth exceeded warning.
I incorporate the useNavigate hook in two distinct files for user login and admin login, both examples are provided below.
To shed more light on why the problem occurs specifically from the second login onwards, it is independent of whether I log in as an admin or a regular user. For instance, if my first login is as an admin, the maximum depth exceeded warning pops up regardless of whether the next login is as a user or an admin. The same pattern applies if my initial login is as a user.
Here are the troubleshooting steps I have executed so far:
- Eliminating navigate from the dependency arrays (resulting in the same warning)
- Omitting the useEffect blocks entirely (which leads to new warnings advising me to place the useNavigate hook within a useEffect hook, causing the login functionality to break completely)
- Doing away with the dependency array altogether (even this results in the same warning)
Error message encountered while logging in as a user:
react-dom.development.js:86 Warning: Maximum update depth exceeded. This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render.

Login.jsx
import { useState, useEffect } from "react";
import axios from "axios";
import { Link, useNavigate} from "react-router-dom";
const Login = () => {
const navigate = useNavigate();
// Rest of the Login component code...
};
export default Login;
AdminLogin.jsx
import { useState, useEffect } from "react";
import axios from "axios";
import { Link, useNavigate} from "react-router-dom";
const AdminLogin = () => {
const navigate = useNavigate();
// Rest of the AdminLogin component code...
};
export default AdminLogin;
Additionally, here's Private.jsx (user home page) and Admin.jsx (admin home page), although I don't believe the issue lies within these files.
